Now the man in Swiss uniform called once more across the chasm: "Attention, Americans I I know you are there; I smell your fire. Also, what you have done is plain enough for me to see--that thing lying over there on the edge of the rocks with corpse-flies already whirling over it! And you had better answer me, Kay McKay!" Then the man in the forest who now was lying flat behind a birch-tree, answered calmly: "You, in your Swiss uniform of artillery, over there, what do you want of me?" "So you are there!" cried the Swiss, striving to pierce the foliage with eager eyes. "It is you, is it not, Kay McKay?" "I've answered, have I not?" "Are you indeed then that same Kay McKay of the Intelligence Service, United States Army?" "You appear to think so. I am Kay McKay; that is answer enough for you." "Your comrade is with you--Evelyn Erith?" "None of your business," returned McKay, coolly. "Very well; let it be so then. But that dead man there--why did you kill your American comrade?" "He was a camouflaged Boche," said McKay contemptously. "And I am very sure that you're another--you there, in your foolish Swiss uniform. So say what you have to say and clear out!" The officer came close to the edge of the chasm: "I can not expect you to believe me," he said, "and yet I really am what I appear to be, an officer of Swiss Mountain Artillery. If you think I am something else why do you not shoot me?" McKay was silent. "Nobody would know," said the other. "You can kill me very easily. I should fall into the ravine--down through that lake of cloud below. Nobody would ever find me. Why don't you shoot?" "I'll shoot when I see fit," retorted McKay in a sombre voice. Presently he added in tones that rang a little yet trembled too--perhaps from physical reasons--"What do you want of a hunted man like me?" "I want you to leave Swiss territory!" "Leave!" McKay's laugh was unpleasant. "You know damned well I can't leave with Les Errues woods crawling alive with Huns." "Will you leave the canton of Les Ernies, McKay, if I show you a safe route out?" And, as the other made no reply: "You have no right to be here on neutral territory," he added, "and my Government desires you to leave at once!" "I have as much right here as the Huns have," said McKay in his pleasant voice. "Exactly. And these Germans have no right here either!" "That also is true," rejoined McKay gently, "so why has your Government permitted the Hun to occupy the Canton of Les Errues? Oh, don't deny it," he added wearily as the Swiss began to repudiate the accusation; "you've made Les Errues a No-Man's Land, and it's free hunting now! If you're sick of your bargain, send in your mountain troops and turn out the Huns." "And if I also send an escort and a free conduct for you and your comrade?" "No." "You will not be harmed, not even interned. We set you across our wire at Delle. Do you accept?" "No." "With every guarantee--"
